I'm having a hard time understanding this article. First of all, a quantum annealer is not a universal quantum computer, just to elucidate the title. Then, it seems like they are comparing a simulation of p-computers to a physical realization of a quantum annealer (likely D-wave, but not named outright for some reason). If this is true, it doesn't seem like a very relevant comparison, because D-wave systems actually exist, while their p-computer sounds like it is just a design. But I may have misunderstood, because at times they make it sound like the p-computer actually exists. Also, they talk about how p-computers can be scaled up with TSMC semiconductor technology. From what I know, this is also true for semiconductor-based (universal) quantum computers.

The submission is an ad. University press releases should not be posted on HN. a press release is just a published paper + PR spin. If the PR spin were true, it would be in the paper. Just link to the paper. https://www.nature.com/articles/s41467-025-64235-y https://www.nature.com/articles/s41467-025-64235-y Title: "Pushing the boundary of quantum advantage in hard combinatorial optimization with probabilistic computers" Abstract: "Adaptive parallel tempering [...] scales more favorably and outperforms simulated quantum annealing" HN title should be changed to match the paper title or abstract.
